The game is Astrocounter of Crescents, a sidescrolling action game where people fight in robot suits: http://translation.derboo.de/crescents.html
In the game, the new suit models seem to allow the pilots to move naturally as the robot (kinda like Neon Genesis Evangelion or Pacific Rim, only with small size robots) through a technology that literally translates to "Organic-Activation-System" or "Bio-Activation-System", but I think that sounds kinda weird. Any better ideas?
Here's the translated description from the game's manual:
"As the name says, a system that covers the entire metabolism of the organism and initiates a widespread overall acceleration process.
The Organic-Activation-System centers around the interconnection of organic life and machine in an outer space environment and was first employed in the Artemis Project prototypes Alent, Bulgidung and Zenith. Artemis Project is currently in the process of intensifying
Biofeedback between Bulgidung and its Pilot."
